AbstractThe phenylcarbamic acid derivatives with N-phenylpiperazine moiety in the molecule have been prepared. The structure has been confirmed by elemental analysis, IR, 1H NMR, and mass spectral data. For the prepared set of the compounds the lipophilicity parameters have been determined. The experimentally obtained lipophilicity parameters have been correlated with theoretical entries obtained by different computer programs based on the neural network and fragmental methods.

The synthesis of hydrazides formed by quinazolin-4(3H)-ylidenehydrazine and dicarboxylic acids, as well as their further modification are described in the present manuscript. It was shown that above-mentioned hydrazides may be obtained via acylation of initial quinazolin-4(3H)-ylidenehydrazine by corresponding acylhalides, cyclic anhydrides and imidazolides of dicarboxylic acids monoesters. Obtained hydrazides were converted into [1,2,4]triazolo[1,5-с]quinazolines that were used as initial compounds for chemical modification aimed to the introduction of amide fragment to the molecule. The IR, 1H NMR and chromato-mass spectral data of obtained compounds were studied and discussed. Obtained substances were studied for anti-inflammatory activity using carrageenan-induced paw inflammation model. Amides of ([1,2,4]triazolo[1,5-с]quinazoline-2-yl)alkyl carboxylic acids were detected as promising class of anti-inflammatory agents for further purposeful synthesis and profound study of anti-inflammatory activity.

Efficient Route

A series of an easy and efficient route for the synthesis of some new 2-amino-3-cyanopyridine (4a-4i) and 2-methoxy-3-cyanopyridine (5a-5i) derivatives were synthesized through the reaction of various chalcone (3a-3i) with malononitrile in presence of ammonium acetate and sodium methoxide, respectively. The constitutions of the all synthesized compounds have been established by the IR, 1H-NMR, Mass spectral data and Elemental analysis. Furthermore, all the synthesized products were screened for their antimicrobial activity.

Phenylazo- and thiazolylazo-2,4-pentanediones on reaction with 2-aminophenol and 2-aminothiophenol yielded a new series of polydentate Schiff?s base ligands. The structure and tautomeric nature of these compounds and their metal complexes were established on the basis of their IR, 1H-NMR and mass spectral data. The spectral and analytical data revealed the condensation of both carbonyl groups of 3-(2-thiazolylazo)- 2,4-pentanedione with 2-aminophenol to form an N2O2 tetradentate ligand. Details on the formation of its [ML] complexes with Ni(II), Cu(II) and Zn(II) and the nature of their bonding are discussed based on analytical, IR, 1H-NMR and mass spectral data.

Several molecules were synthesized like 8-ethoxy-4-methyl-2-amino-(3’-chloro-2’-oxo-4’-substitutedaryl-1’-azeti-dinyl)-quinolines 8-12 and 8-ethoxy-4-methyl-2-amino-(2’-substitutedaryl-4’-oxo-1’,3’-thiazolidin-3’-yl)quinolines 13-17 from 8-ethoxy-4-methyl-2-(substitutedarylidenylimino amino)-quinolines 3-7, and screened to evaluate their antibacterial activity against numerous strains of bacteria        in vitro. The structures of new compounds were established on the basis of their elemental analysis, IR, 1H-NMR and mass spectral data. The results showed that three compounds 10, 11 and 16 were found to exhibit promising antibacterial activity as compared to the standard drug amphicillin.
